Birel gokart ROTAX DD2

RACING LINE - ROTAX DD2

Birel’s proposal for the Rotax DD2 Trophy, which was the object of deregulation in terms of chassis, will be, as well as the much tested and winning model CRY 31-RX, also a version with CRY 30-RX chassis.
For the Trophy promoted by the Austrian firm, Birel drivers will be able to choose between two different technical solutions: the 31 mm chassis version is more suited to particularly slippery tracks, whereas the 30 mm chassis version is more conventional, with very good “smoothness” and best suited to dry tracks.
Both models feature a special rear axle which allows the two-speed engine with direct drive on the (40 mm) axle to be fitted and HQ Freeline accessories, such as magnesium rims and anodised components in Motorsport livery.
The braking system is a last-generation model, similar to the version featured on the 125 cc range, with 150 mm discs at the front and 200 mm discs at the rear. The Trophy kit also features the gearbox levers by the steering wheel and the bumper in compliance with regulations A, both supplied by Rotax.

CRY 30-RX	CRY 31-RX
It is ideal for the youth categories of the Austrian one brand, as it is very “free” and it can emphasize at best the engines with less power. But more in general, it is efficient on “gripped” tracks and with summer heat. Its versatility makes it competitive on every track and in every condition.	It offers more grip compared to the version with 30 mm tubes and also more precision while entering the bend and stopping. It fits for people who prefer a precise chassis that, however, adapts at best to every track condition, always resulting a perfect compromise.
